The surprise release of a new Rihanna single, Work, went smoothly on Wednesday morning as the song shot to the top of iTunes charts in dozens of countries.

According to Billboard, Rihanna inked a deal with bosses at Tidal to exclusively release the record through their site.

In 2013, Roc Nation head/Rihanna mentor Jay Z also offered his last studio album Magna Carta Holy Grail as a free digital download through a partnership with Samsung. The service is also making a limited number of complimentary download codes available to subscribers and non-subscribers alike, all of which come with a 60-day free Tidal trial. Mere hours after the first single off Rihanna's hotly anticipated new album dropped, the whole album has leaked.

The video for the eighth room was released on Wednesday, and features the singer entering a room where two girls are asleep on a bed. The song isn't up on YouTube, SoundCloud or Spotify, but is available by visiting Tidal's homepage and left-clicking on the artwork. The following appears to be the tracklist for Rihanna's Anti, but Roc Nation hasn't yet confirmed that it's official: 1.

Anti does not include FourFiveSeconds, a song that Rihanna released a year ago in a collaboration with Paul McCartney and Kanye West.

As well as collaborating with Drake, Rihanna spits bars with SZA on a track called "Consideration" and there's a cover of Tame Impala's "New Person, Same Old Mistakes", re-dubbed "Same Ol' Mistakes".

Rihanna will head out on a worldwide tour in support of the album later this year but will bypass San Antonio, instead stopping in Austin, Dallas and Houston on her trip through the Lone Star State. Similar to her previous albums, the 13-track LP blends R&B;, hip-hop, pop and reggae.
